Specification of Letters Patent.

Patented Feb. 12, 1918.

Application filed April 24, 1916. Serial No. 93,135.

To all whom it may concern:

Be it known that I, HARRY H. Sermons, a citizen of tie United States, and. a resident of the city of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Metal Vestibule-(Jar Diaphragms,- and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the numerals of reference marked thereon, which form a part of this specification.

his invention relates to an improved type of metal vestibule car diaphragm wherein a novel and efficient construction is utilized to permit expanding movements of the diahra m with reference to a car on which it is mounted to take place, and with the parts in all positions of adjustment acting efiiciently to provide a weatherproof passage on the interior of the vestibule diaphragm.

It is an object therefore of this invention to provide a metal car diaphragm construction wherein the parts are adjustably associated with one another to permit expansion and contraction of the diaphragm as well as weaving movements thereof, due to relative movement taking place between coupled cars on which the diaphragms are mounted, and yet operating to provide a weatherproof passage between the cars at all times and in all positions of adjustment of the diaphragm members.

It is also an object of this invention to construct a metal car diaphragm construction comprising stationary and movable sections with the stationary sections constructed to receive the movable sections telescoping therewithin and in sealing relation therewith, and with the movable members of the interfitting diaphragm sections adjustably associated with one another to permit weaving movements of the diaphragm sections to take place due to relative movements between the cars on which said diaphragms are mounted. a

It is furthermore an object of this invention to provide a metal car diaphragm construction wherein a novel association of members comprising the stationary Et11Cll11OV able sections of the diaphragm, is provided to permit ready expansion and contraction of the diaphragm sections with respect to one another and to permit flexing thereof due to variations in movement between cars coupled to one another between and upon which the diaphragms are mounted.

It is finally an object of this invention to provide a simple, efiicient metal diaphragm construction readily adapted for use on standard types of cars.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure 1 is a fragmentary side view with parts broken away and shown in section, of a pair of diaphragms connected one to another and mounted on the ends of cars coupled together.

Fig. 2 is a fragmentary detail section taken on line 2-2 of Figs. 1 and 6, with parts omitted and parts shown in elevation.

Fig. 3 is a fragmentary detail section taken on line 3-3 of Fig. 1.

Fig. 4 is a fragmentary detail section taken on line H of Fig. 3, with parts in elevation.

Fig. 5 is a fragmentary detail section taken on line 55 of Fig. 1, with parts omitted and parts shown in elevation.

Fig. 6 is a fragmentary top plan view of the diaphragm construction, with parts broken away and parts shown in section.

Fig. 7 is a. modified form of construction illustrating another type of connection of the side wall members of the movable dia- ];)hragm section to the face plate of the diaphragm.

As shown in the drawings:

The reference numeral 1, indicates as a whole the end of a car, and movably mounted beneath the platform thereof (not shown) is a channel 2, forming the front member of a platform buffing mechanism of any usual and well known construction secured and supported on which is a vestibule diaphragm face plate 3. As clearly shown in Fig. 1, an auxiliary bufling mechanism for the upper end of the face plate 3, is also provided, comprising a horizontally rearwardly directed rod 4, securely attached upon the rear surface of the face plate 3, extending rearwardly and slidably through certain frame members of the car body, and having a compression spring 5, coiled thereabout, adapted to resist inward sliding movement of said rod with similar movements of the face plate and vestibule diaphragm. Forming a construction at the upper' porting the end portion of the curved root of the car.

Secured in any suitable manner to the front surface of the vertical frame plate '7, and projecting outwardly therefrom in 7 parallel relation to the gabled top or root tending flange,

'trapezoi lal section,

of less width than the plate (3, is another gabled plate 9, which is flanged downwardly at its side and forward margins and attached to a horizontal ceiling plate 10, of the vest'bule of the car, affording a compartment through which the associated rod 4:, and spring 5, extend.

Secured in upright position on each side of the end of the car body are large channels, having an inner wall 11, and an outer wall 12, with the forward or outer margins of plate "6, and

said respective walls flanged outwardly as clearly shown in Fig. 3. Provided upon each side of the car body are upright I-beams 1'3, and the respective channel members 11-12, of the vestibule diaphragm are secured thereto by angle irons 14L and 15, respectively, rivetedto the-flanges ofsaid I- beams and t0 the side walls 12, of the channel members.

The elements of the movable section of the diaphragm are connected upon the face plate '3, and for this purpose a rearwardly tapered 'gabled roof plate member 16, flanged at its forward margin and riveted to the rear surface of said face plate, as clearly shown in Figs. 1, 2, and 6, and extends rearwardly beneath the gabled top plate 6, and over the gabled top wall of the compartment or abutment member 9. Near its side margins, guide or abutment members 17, ;of as shown in Fig. 2,

are provided, each consisting of aplate bent longitudinally into trapezoidal form' and riveted or brazed beneath the surface of the roof plate 16, near the side margins thereof, and spaced therefrom to afford a recess therebetween. Slidably inserted in the recess between the trapezoidal abutment members 17 and said roof plate 16, are flat trapezoidal shaped wing plates 18, which, at their forward ends are connected by means of a pivot 19, to the roof plate 16, and each'provided with a downwardly exthe rear end of which fits the channels-11-12, of the hragm section, as clearly and 6. As shown in Fig.

slidably within stationary 'diap shown in Figs. '5

v rounded portion therefor, or in other words prevent 178N314 5, the top horizontal. margin of "the outer wall 12, of the channels 11-12, merely extends upwardly to afford an abutment against which the downwardly turned flange of the wing plate gins flanged inwardly in horizontal posiwalls of the movable section of the dia-' phragm each comprising resilient angled divergent walls 21 and 22, respectively, integrally connected in a rounded be'ad'portion 23, and with the rear margins of said respective wall members provided with strips of sealing material 24, which, owing to the resiliency of the wall members2l and 22, are thrust into sealing contact with the interior surfaces of the channelwalls 11 and 12. The uppermargins of the wall members 22, are turned horizontally inwardly and provided with sealing strips 20, which bear upwardly beneath the flat surfaces of-the trapezoidal abutment members 17, of the roof plate 16. V r V For the purpose of attachment of said resilient side walls 21-22, to the face plate 3, a pair of plates-25 and 26, are bolted on the rear surface of the face plate with the margins thereof curved, asclearly shown in Fig. 8, to afford a cylindrical-recess within which the rounded or beadedportion 23, of said divergent wall members 21 "and 22, fits and is capable of movement therein. Ass

18, may contact, while theinner walls 11, have their upper mar-' clearly shown in-Fig. 4:, at certain points in I the length of the beaded rounded portion 23,

of said side wall members, the-metal is cut away, also the rounded margins of plates 25 and 26, are cut away in almement with the cut away portions of bead 23, and inserted inthe alined notches thus formed are blocks 27, which are brazed or rigidly secured to plates 25-26, and which serve to prevent longitudinal movement of the 23, in the retaining plates cal movement of the side walls 21-22, of the movable diaphragm section with reference-to the faceplate 3. Amodification of the connection of the sidewall members 21--22, of the movable diaphragm section to the face plate 3, is shown in Fig. 7, wherein in place of the plates 25. and 26, plates 28 and 29, are provided bolted flat upon the rear surface of the face plate 3, and with their adjacent margins turned inwardly and curved to afforda cylindrical recess to receive the beaded or rounded portions 25, of the side wall members 21 -22. r

A sealing mechanism is provided'for the roof plate16, at the point at which the-same slides inwardly within the car end beneath the gable top plate 6, and for this purpose, as clearly shown in Figs. 1 and 5, a pair of angled plates 30 and 31, respectively, are secured in inclined position on the built up end plate member 8, of the car projecting outwardly therefrom with their lower margins spaced from one another and having mounted therein a sealing strip 32, normally impelled downwardly into contact with the top surface of the gabled roof plate 15, by springs 33.

The operation is as follows:

Due to the flexible connection between the face plate 3, and the side wall members 21- 22, of the movable diaphragm section, a flexing or weaving movement between the same is readily permitted and furthermore,

owing to the fact that no rigid connection exists between the gable roof plate 16, of the movable diaphragm section and the side walls 21-22, thereof, adjustments with respect thereto due to variations in movement of the diaphragm with respect to the car, are also readily permitted. The telescoping movements of the movable diaphragm section composed of the side walls 21-22, and roof plate member 16, are readily permitted, owing to the fact that the resilient side wall members 2l-22, telescope within the fixed upright channel members l112, of the stationary diaphragm section, and the roof plate member 16, moves beneath the gabled stationary top plate roof member 6, sliding beneath the sealing strip 32, provided at the upper end of the car.

A certain angular movement of the face plate 3, with respect to the elements of the movable diaphragm section is permitted, and when such movement takes place, of course the face plate has a hinged action on the cylindrical or beaded portions 23, of the side walls 21-22, but the gabled roof member 16, moves as a unit therewith, and owing to the fact that the side margins thereof are tapered inwardly, as shown. clearly in Fig. 6, the same is capable of swinging laterally with respect to the ele ments of the stationary diaphragm section. A seal between the gabled roof plate mem ber 16. of the movable diaphragm section and its side walls 21-22, is eflected by the pivotally mounted wing plates 18, which engage in the recess provided therefor beneath the side margins of the roof plate 16, and are turned downwardly to overlap the upper edge of the side wall members 22. As a consequence, when the swinging movements of the roof plate member 16, take place as the vestibule face plate 3, is caused to assume an angled position, the wing plates maintain substantially the same relation with the side walls 21-22, and the roof plate 16, slides with reference thereto, the seal, however, being always maintained, and when the associated roof plate 16, and

of the class described,

wing plates 18, move inwardly with respect to the stationary diaphragm section, said wing plates 18, engage within the channel members 1112, contacting the inner surface of the walls 12.
